Im September 2019 haben wir uns kurzfristig entschieden von der Gas- auf Wärmepumpenheizung umzustellen. Das Pr0jekt lief sehr schnell ab. Anfang Oktober hatten wir die Offerte. Am 25. Oktober erfolgte die erfolgreiche Abnahme. Seither läuft die Anlage einwandfrei. Zu erwähnen ist noch, dass wir mit dem Luft-/Wasser-Wärmepumpe (Viessmann Vitocal 300-A) unter anderem wegen des sehr leisen Betriebs sehr zufrieden sind.

Ich gebe der Firma Tschantre für ihre Arbeiten 5 Sterne

Wenn was mit der Heizung nicht stimmt, wurde es durch euch prompt erledigt.

Ich kannte schon seinen Vater absolut seriös und kompetent. Da passt der Spruch: Qualität hat einem Namen
